Abstract: A door, in particular a high-speed industrial door, with an intelligent door leaf is disclosed. The door has a door leaf which is guided by lateral guides and covers a door opening, and which has a first and a second side, a driving means for moving the door leaf between an open and a closed position, a door control means for controlling the driving means, as well as an electrically self-sufficient door leaf means arranged in the door leaf. The door control means also has a first communication unit. In addition, the door leaf device comprises at least one sensor unit for detecting at least a physical quantity, an energy converter which converts non-electrical energy into electrical energy, a second communication unit and at least one actuator unit. The first and second communication units communicate wirelessly with each other.

Abstract: The invention relates to a device (100) for detecting the falling of a door leaf (2) of a door (1), preferably a high-speed industrial door (1), the device (100) for detecting the falling of a door leaf being provided on or in the door leaf (2). The device (100) for detecting the falling of a door leaf comprises a means for detecting the acceleration of said device (100) in at least one falling direction of the device (100), and a wireless communication unit (200) for emitting a falling warning signal in the event of a falling of the door leaf (2) being positively detected. The positive detection of the falling of the door leaf (2) is based on an acceleration being detected in the falling direction.

Abstract: A safety device for externally driven systems for protecting the movement of a system component against undesired collision with an object lying in the movement path of the system component is described, the system component to be monitored being capable of being moved in a guided fashion along a predetermined path (door plane ET). The movement path of a leading edge of a system component is preferably monitored by an optical beam protection, preferably on the basis of infrared beams, which protection has at least two, preferably at least three or a plurality of preferably parallel beams which are arranged staggered in the direction of movement of the system component and which are emitted on one side of the system component and received or reflected on the other side. The safety device has a safety circuit with which the movement of the system component is stopped or reversed if an obstacle is sensed in the movement path of the system component.

Abstract: A safety device for preferably vertically moving, motor-driven doors such as, for example, segmented doors or rolling shutter doors whose door leaf is capable of being moved in a guided fashion is described. The movement path of a leading door edge is monitored by a preferably optical beam protection, preferably on the basis of infrared beams. The beam protection has at least two, preferably at least three or a plurality of preferably parallel beams which are arranged staggered in the direction of movement of the door and which are emitted on one side of the door and received or reflected on the other side of the door. Furthermore, a safety circuit is provided with which the closing movement of the door is stopped if an obstacle is sensed in the movement path of the door.
